Dukonnector, a launch i have made like a year ago
gives the user the ability to Configure his DosBox inside it and add
new dos games to it and play online with them, it has a server list
game rooms global chat and all you need.

it's purpose used to be only launching Duke3d games with different ports,
but in time ive decided to add more Build games, and eventualy ive decided
to let the use add his own dos games and dosbox too.
I hope it will serve all of you DosBox Multi-gamers well.
